AI Game Team

Design, code, pacing, and UI feedback all move together instead of one brittle prompt dump.

Browser-Playable Instantly

Every build stays in the browser, so feedback loops stay short and share links stay useful.

Multiplayer Ready

Prompts, servers, and room-state hooks are already shaped for co-op or competitive ideas.
